How is the +5dB gain increase produced inside the Schoeps CMC5 body?


With transistors.

Literally, there is a small amount of voltage gain and a massive amount
of current gain from the front end FET.

The output stage is just dual cathode followers, producing only current
gain with no voltage gain.

( Scott mean to say " emitter followers", not cathode )



I was going to say that !

Talking about the 'cathode-world' I got a 450VDC belt two days ago from
a guitar amp I am working on. Thought I had discharged everything, but
obviously hadn't. Yesterday could still feel where it went in my left
thumb, and out my right middle finger ! OK today. Screwdriver in left
hand went for miles !
